In 1873 the Italian physician Camillo Golgi revolutionised neuroscience by introducing the reazione nera (Golgi stain), a silver chromate method that randomly impregnated a small number of neurons in their entirety (cell body, dendrites, and axon) making it possible for the first time to see the full architecture of individual nerve cells within dense brain tissue (Golgi, 1873). This technique was later mastered and extended by Santiago Ramón y Cajal in the late 1880s–1890s, who used it to demonstrate that neurons are discrete cells rather than a continuous network, founding the neuron doctrine and paving the way for modern understanding of neural signalling and, ultimately, neurotransmission at specialised contact points later termed “synapses” by Charles Sherrington (1897), work for which Golgi and Cajal jointly received the 1906 Nobel Prize despite holding opposing interpretations. From a Christian perspective, this unfolding clarity about the ordered complexity of the nervous system resonates with biblical affirmations that humans are “fearfully and wonderfully made” (Psalm 139:14) and that creation reflects intelligible order inviting careful study (Proverbs 25:2), suggesting that scientific insight is not a rival to faith but a means of stewarding God-given reason to alleviate suffering. Practically, Golgi’s stain underlies modern neuroscience that informs treatments for mental illness, neurodegenerative disease, and brain injury, contributing to personal wellbeing through better diagnosis and therapy, and to societal health by shaping public understanding of brain–behaviour relationships, reducing stigma, and guiding ethical care for the vulnerable, an expression of loving one’s neighbour through knowledge put to service (Mark 12:31).
